Basically, for the number line, there is an open circle on the 3 and the line goes to the left of 3.

By rounding of the following number to the nearest thousand is 2000.

Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.

Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.

The lowest overall weight that may be achieved is 220.35 grams

Weight is the amount and quantity of bulk or heaviness.

mass is typically defined as the force of gravity, which is equal to the body's mass times the local velocity of gravity.

As the weight of the smartphone is stated to be 210 g to two significant numbers, we may conclude that its true weight is between  205 g & 215g.

We may estimate that the case weighs between 15.35g to 15.45g because it is said to weigh 15.4 g  to one decimal point.

So, 205+15.35 = 220.35 g  is the absolute minimum weight that the phone and case may weigh together

Hence, 220.35 g  is the lowest feasible overall weight.

The true inequality from the list of options is (c) -x - 6 > -3.5

To determine which inequality is true when x is -5, we need to substitute -5 for x in each inequality and simplify.

a) -x – 6 < -3.5

Substituting x = -5, we get:

-(-5) - 6 < -3.5

5 - 6 < -3.5

-1 < -3.5

This is false, so option a) is not true.

b) -x – 6 > 3.5

Substituting x = -5, we get:

-(-5) - 6 > 3.5

5 - 6 > 3.5

-1 > 3.5

This is false, so option b) is not true.

c) -x - 6 > -3.5

Substituting x = -5, we get:

-(-5) - 6 > -3.5

5 - 6 > -3.5

-1 > -3.5

This is true, so option c) is true.

Hence, the correct option is (c) -x - 6 > -3.5

Answer:

Step-by-step explanation:

Opposite angles of an inscribed quadrilateral are supplementary. Inscribed angles are half the measure of the arc they subtend. (The latter statement can be used to prove the former one.)

Using these relations, we have ...

  C = 180° -E = 180° -85° = 95°

  D = 144°/2 = 72°

  F = 180° -D = 180° -72° = 108°

Answer:  Draw a straight line through (0, 16) and (1, 14)

The graph is below.

=========================================================

Explanation:

There are at least two approaches we can take

-----------------

Method 1

Plug in x = 0 to find that....

y = -2x+16

y = -2(0)+16

y = 16

The point (x,y) = (0,16) is on the line. This is the y intercept

Repeat similar steps for x = 1

y = -2x+16

y = -2(1)+16

y = 14

The point (1, 14) is also on the line

Plot the points (0, 16) and (1, 14). Then draw a straight line through them to complete the graph for y = -2x+16

You only need 2 points at minimum to draw a linear graph.

The graph is shown below. Ignore the stuff in red.

-----------------

Method 2

Compare y = -2x+16 to the form y = mx+b

The y intercept is where the graph crosses the y axis. In this case, it's at the location (0, 16)

Start at this point and move down 2 units and to the right 1 unit to arrive at (1, 14) which is another point on the line.

The stuff in red shows this motion of "down 2, right 1"

note that slope = -2 = -2/1 = rise/run

rise/run = -2/1

rise = -2 = go down 2

run = 1 = go to the right 1

Step-by-step explanation:

Test statistics is used in hypothesis testing to find the conclusion. Test statistics are T-values which are used in testing a hypothesis and deciding whether to accept or reject the null hypothesis.

Test statistics can be calculated with the following formula:

Z = x - u / s /\(\sqrt{n}\)

The sum of these 40 sampled numbers follows option D: normal distribution, if X follows Poisson distribution.

The likelihood that a certain number of events will occur in a specific period of time or space, provided that they do so with a known constant mean rate and the Poisson distribution describes the distribution of events, regardless of the time since the previous event. When the mean is high, the sum of the Poisson distribution resembles a normal distribution.

The "normal distribution," a continuous probability distribution that is symmetrical at the mean and has a bell-shaped curve. It is also known as the bell curve or the Gaussian distribution. Several natural phenomena, including height, weight, blood pressure, and others, have a normal distribution.

54 + 63 = 13 * 9 is the expression obtained as the product of a number and relatively prime addends.

A prime number is a number that can be divided only by 1 and itself.

54+63                                   (given)

We now have to find the sum of the given numbers as the product of relatively prime numbers.

In order to find the numbers we will find first sum and then factor

Sum=54+63=117

Factors of 117 are 13 and 9

117 = 13 * 9

13 and 9 are relatively prime because the factor of 13 and 9 is 1.

Therefore, 54 + 63 = 13 * 9 is the expression obtained as the product of a number and relatively prime addends.

Hence, The Isomorphism between Two-Well-Ordered Sets W1  and W2  is UNIQUE

Make a Plan: Understand the Problem

We need to Prove if Two-Well-Ordered Sets W1  and  W2 are ISOMORPHIC, Then there is ONLY ONE ISOMORPHISM.

PROVE the Statement

1 -Assume there are Two Isomorphisms  f  and g between W1  and W2

2 - Define a Set:

A = {x ∈ W1 |f(x) ≠ g(x)}

3 - If A is Empty, Then f(x) = g(x) for all x ∈ W1, and the Isomorphism is Unique.

4 - If A is Non-Empty, Then Since W1 is Well-Ordered, There Exist a Least Element  a ∈ A

5 - Since f and g are Isomorphisms, f(a) and g(a) are the Least Elements in their respective images in W2.

6 - Since f(a) ≠ g(a), One of them, say f(a), is less than g(a).

7 - Let b = f^-1(g(a)).  Then b > a because f is an Isomorphism and f(a) < g(a).

8 - Since b > a, We now have f(b) = g(b) because, a is the Least Element in A.

9 - However, f(b) = g(a), Which Contradicts the Fact that  f  and g  are Isomorphisms

Hence, The Isomorphism between Two-Well-Ordered Sets W1  and W2  is UNIQUE

The resultant of the force that acts in opposite directions is 7 N.

We have,

We know that the resultant force is the force that has the same effect in magnitude and direction as two or more forces that is acting together. We have to note that the force that is actinmg on an object is a vector quantity. The implication of this is that the magnitude and the direction of the forces that are acting on the body is very important.

By the use of the law of vectors we can be able to write in the case of the question that we have here, we can see that the forces are acting in the opposite directions. The implication of this is that we would have to subtract the forces so as obtain the resultant force.

We have to note that when we have opposite forces, one is said to be positive and the other negative and the resultant force can be found by subtraction. As such the resultant force can be obtained from;

Let the +B force be 12 N

Let the -B force be 5N

12 N - 5 N = 7 N
